Starting a thread to show off our favorite tools, be they for sketching, designing, or whatever's your treasure. I'm a gearhead and love nice tools, so I know I'll post a bunch and hope all you other tool geeks do as well.

One from the "fine measuring tools" drawer of the toolchest (Sharpie for scale, glass container to hold stuff down for photographing).

Keuffel & Esser 100' tape:_made in the U.S._folding hand rewinder knob w/detent capture_tape end has folding hook to anchor one end as you walk it out_real leather wrap_weighs 4 lbs. -ish_rollers for smooth retraction of tape

I estimate its age at 60+ years. Works like a charm. Though to be honest, my need for a 100' tape is pretty infrequent! Good for exterior building and small lot measurements.
